For those who are not really keen on using multifilaments and don't want to dabble with hybrids but require that softer feel and joint protection monofilaments made of various compounds other than polyester or co-polys with elastomers (a.k.a. rubber) seem to be the next best thing, so I thought it would be great to have a list of those with peoples opinions consolidated in one thread...

Polyamid monofilaments:
Angell Halo 1 - discontinued
Babolat RPM Soft
Babolat Origin - discontinued
Diadem Evolution
Double AR 25 - discontinued
Double AR 666
Double AR Furia
Dyreex Black Mist
Infinite Molecular Gut Rough
Infinite Silky touch
Still In Black X8, X10 and X12


Elastomer co-polys:
Isospeed Cream
Isospeed Rexxxer
MSV Swift
Stringlab Elastospring
Toalson Polywire Plas - discontinued
Yonex Polytour Air

Double AR 666 1.30 (I've tried this, it's very good.plays like a softer copoly)
Double AR Furia 1.22 (have not tried)
Infinite molecular gut rough 1.22 (soft and comfy, nice spin, but stays out of place in the mains with poly crosses)
Infinite Silky touch 1.30 (have not tried)
Stringlab elastospring white 1.28 (waiting for this to arrive)
all based on polyamide

Thanks, I've updated the list. Haven't heard about these except for Double AR 666 but didn't seem to find it when I've browsed through their site.

Any deeper insight on these and how they compare to the bigger more known brands?
Stringlab Elastospring is made in Austria so that can mean the string is actually made by Isospeed and is most likely very close or identical to Isospeed Cream. I didn't see "polyamide" in its description on the official site (there is mention of polyamide on another site but I'd go with the official source), however everytime I browse those italian sites I get a feeling their original content is translated by Google Translator and thus I'm not getting the entire marketing spiel - I don't speak Italian so I either go to the English versions of the sites or use Google Translator.

I wouldn't trust the description you've quoted. FIrst of, it is different than what is written on the package and the official website. Secondly Silverstring is a monofilament so why does the quoted description mention fibers - plural.

Hey, what do you know about this string? I was sent a packet to try, and I can't find anything about it.
It's a replacament of Origin. It's called RPM Soft.

@Automatix

Hope the grommets are installed and your frames are happy. :) Also curious how Evolution feels compared to both Origin and Cream/YPTA. I was not a fan of Origin at all. I have two partial reels remaining for clients who do like it, and you know how much I use Cream and YPTA. I am probably gone to order a couple of packs of Evolution, but I know I won't like it if it is anything similar to Origin. :confused:. My reasoning for purchasing it is simply for clients who want an Origin-like string.

I can always offer it as a free playtest to the clients and see if they like it but would love to learn more from players who use it in either full beds or hybrids.

In general are these strings doing better than « soft polys » with regards to tension loss and duration of playability? I have read good things about Isospeed cream but was not particularly amazed by Yonex Polytour Air. My tennis pal like it very much though.

How's the snapback? Does it allow sliding? Does it notch?

Not sure on snapback with the evolution as i'm using as a cross, it doesn't get stuck out of place. The Solstice will notch eventually but very slowly when paired with the soft cross string.

Evolution is very close to Origin. Differences are miniscule so definetly not for You. If you're looking for a replacement for Origin for your clients it should do, it's also cheaper. RPM Soft is on the way to the stores though...

I meant does it allow good snapback from the main?

I've tried a few times and it does allow pretty good snapback for mains as a cross

https://imgur.com/N0RtMSW

first pic is just a new string cross section

but the rest are from a used stringbed of solstice black main/evolution cross

it doesn't actually notch but rather flattens in the cross, I really liked that it allowed the mains to slide until the mains broke

last pic is the solstice black which did notch

I did experiment with the evolution in main and solstice in the crosses, in this configuration the evolution in the mains will eventually notch

I am fine with Babolat Origin being discontinued. The string was super comfortable but (for me) just no spin or control.

I am disappointed TW stopped carrying Double AR 666. I love that string!! I use 666 in the mains with Ashaway Monogut ZX in the crosses. Very good spin and control for a nylon (polyamide). Good durability. Long playing life. I was able to purchase a reel of it from Italy. http://www.doublear-shop.it/

Just a FYI. I've heard Polywire Plas is suppossed to be released outside of Japan in 2022. We have Cream and YPTA but the more, the better.

@Casper777 nice find mate!
Just to elaborate these are monofilament polyamids so are in line with Babolat Origin and Diadem Evolution.

Translated description:
4 years of research and development in France in partnership with the world leader in polyamide monofilament strings to develop this innovative string that will meet the expectations of many regular players or competitors!

The X 12 string uses patented Dual Dynamics ® technology that meets performance and protection goals without compromise. Its 100% polyamide composition and its simple structure offer a double benefit: a shock-absorbing inner structure associated with an elastic outer skin.

Role of the heart: it dampens the impact of the ball, absorbs vibrations and harmful energy for more comfort and touch. The skin thus stores a maximum of energy.


Role of the skin: very elastic, it returns all the stored energy by shortening and promotes explosiveness when struck like a spring!

The results of a study conducted for the manufacture of this string demonstrate that monofilament polyester strings have qualities of control, wear resistance and responsiveness. But that this type of ropes is rigid and generates vibrations which can cause fatigue for the arm.
Conversely, multifilament strings are more flexible, more elastic and require less effort during the strike but they are less resistant and less reactive (therefore, less control).

The specific construction of the X12 string makes it possible to mix the qualities and advantages of each of these 2 families of strings to obtain an overall result.

The Still in Black X12 allows you to have powerful and precise strikes with a rather "dry" touch but to keep a playing comfort which will protect the muscles and tendons of your arm.

With the comfort qualities of a multifilament, the X12 is nevertheless a monofilament that increases the performance of the player. It amplifies the strike force while preventing the risk of injury. It also offers a long and very soft impact when hitting for better touch and high explosiveness when hitting .

The X12 has an elongation of 12% at a tension of 25 kg, which is 4 times greater than a Polyester monofilament and just as much or even more than a multifilament ...

The difference between the Still in Blanck X10 and X12: the playing characteristics of these 2 strings are close but the x10 deforms a little less on impact and offers a more explosive touch than the X12 which will be softer.

So, I did skim the whole thread so I may have missed it... I apologize if so.

I got in my lovely Isospeed Rexxxer, and see that its core is elastomer poly, the surface co-poly. Elastomer makes me think... like, silicone rubber? I'm curious as to what the thinking behind this is. As in, what benefits are they intending to confer on the string overall via this material? My layperson's guess would be something to do with comfort.

Just bumping this thread up and a question to you seekers of comfort:
Any new offerings from the rubber polys or monofilament polyamids?
Or maybe you'd like to share your experience with the ones on the list?

The more we share the easier it will be for others!

I'm thinking of ordering Still in Black X6 - the stiffest monofilament polyamid available from that particular manufacturer. Not a lot of info about it and didn't have much luck with getting stiffness numbers from the producer.

You mean X8?? Dont see any X6...

Sorry I didn't read the thread title correctly. my mistake

Added under "Honorable multifilament mentions" since it is a multifilament. ;)

@g4driver anything you'd like to share about that string?

Yes..it is expensive. :(. We need a thread of all the multiestyers.

These strings are not even remotely the same. Triax is almost a poly whereas RPX shreds like a multi and breaks very quickly. I wouldn't suggest RPX to anyone and I wouldn't suggest Triax to anyone with elbow issues. Cream is far more comfortable.

Didn't try RPX so can't comment on that but I didn't find Triax to be almost poly like.

Does vinyl or olefin polyester count? Polyfibre lists these as the string material on their website.
I was wondering if someone brings up olefin comps.
I deliberately didn't include such strings because I am not entirely sure they're soft due to these compounds or due to the crazy tension loss. Polyfibre olefin strings are notorious for extreme tension drop. From my experience the absolute king of tension loss is Polyfibre TCS.
As for vinyl. I've tested both Tour Player and Tour Player Touch and they are not soft strings.

@brownbearfalling do you have any experience with examples of either strings mentioned above?

According to the Ersa Pro Stringer Magazine report, Msv Swift is based "on polyester and elastomer-based materials, offering remarkable responsiveness and an excellent progressive feel at impact". I suppose we should include it to the list.
